Salt & Pepper SHAKERS

I wanted to create Salt & Pepper shakers with a twist.

The idea is that when you use them they'd make a sound like a shaker musical instrument.

This was achieved by creating a double wall with beads in between to create the sound.

Step 1: Equipment

1. Aluminum cylinder - 38/1.25 mm

2. Plexiglass cylinder - 25.4/1.59 mm

3. 3D Printed tops and bottom

4. Rubber plugs - 12 mm diameter

5. Beads

6. Sanding paper, chisels

7. Miter saw or hand saw

8. Glue, I used Bison Nexus Glue

9. Clear shiny spray paint

Step 2: Cut the Cylinders to Size

I used a miter saw with the right blades for cutting the aluminum and then the plexiglass. I choose 10 cm as the length.

You can use a hand saw for this as both materials are easy enough to cut manually.

I then used a chisel to that off the excess edges on both materials.

For the aluminum parts I sanded them and then spray painted with a clear coat to avoid scratches.

Step 3: 3D Printing

3D Printing was the fastest way I could think of for printing the tops and bottoms of the shakers. Although if you don't have a 3D printer this is the most expensive part of the project.

I designed it so that they would fit into the external cylinder while holding the inner one in place. I also designed them so that when filling up the salt/pepper you wouldn't have access to the beads.

Attached are the SolidWorks files and the STLs.

I choose the obvious black and white for the tops and a light shade of pink for the bottoms. In hindsight I should have gone for a stronger color or just black and white for the bottoms. The pink came out a bit too pale.

Also the tops are a bit rounded, depending on the printer you're using and the resolution you may want to have them straight. The finishing may look nicer.

Step 4: Assembly

Starting at the bottom, I assembled the bottoms on the plexigalss and then glued the outer part of the plastic bottoms into the aluminium cylinder. I made sure no glue would have any contact with the salt/pepper later on.

I then washed all of the parts thoroughly and wiped dry the aluminum to avoid water drops on the surface.

After they dried entirely (its important to wait enough so that the salt and pepper don't get all wet), I used 2 teaspoons of beads per unit. You can experiment with different types and quantities to get the sound you like. I wanted it to be obvious there's something different here but without making it annoying.

Then put on the top part. Again only gluing the outer edge to the aluminum.

Turn it upside down to fill up salt/pepper and push the rubber plug in place.
